Subject [jira] [Commented] (HDFS-3830) test_libhdfs_threaded: use forceNewInstance
Date Tue, 21 Aug 2012 21:05:38 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3830?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13439043#comment-13439043

Colin Patrick McCabe commented on HDFS-3830:

I tested the patch by running test_libhdfs_threaded.  Before doing so, I added the jars from
share/hadoop/hdfs and share/hadoop/common to my CLASSPATH.  (I am working with the tarball
layout here.)

Without this patch, the test fails intermittently.  The failure mode that I saw was an exception
from one thread about the FileSystem being closed (because someone closed FileSystem shared
by all threads, and it doesn't reference-count.)

> test_libhdfs_threaded should create new FileSystem instances with newInstance, to make
sure that the test doesn't break because of interference between the different threads.
